With Facebook's announcement that they are moving forward to enable cross-platform chat using XMPP/Jabber the chat wars are effectively over. With Facebook and Google on the XMPP. bandwagon it's just a matter of time until the proprietary services either switch or become totally irrelevant. It's about time this happened. This was the world's biggest no-brainer: Using Facebook Chat via Jabber.
Since the launch of Facebook Chat, we've received a lot of positive feedback from users about being able to connect instantly with their friends on Facebook. With Chat fully launched and growing steadily, we've started working on more new features to enhance the Chat experience.
Right now we're building a Jabber/XMPP interface for Facebook Chat. In the near future, users will be able to use Jabber/XMPP-based chat applications to connect to Facebook.
